Quick answer: a 2-1 buydown is a seller- or builder-funded escrow that lowers your effective mortgage rate by 2% in year one and 1% in year two, then returns you to your permanent note rate from year three on. On a $300,000 Ohio loan at a 6.5% note rate, that means a $1,520 principal-and-interest payment in year one instead of $1,896, and the whole thing costs about $6,828, which the seller typically pays as a credit at closing. You still qualify at the full 6.5%. Here’s the math, the rules, and the honest part nobody puts in the listing flyer.
I do a lot of these in Cincinnati and Columbus, and they’re my favorite play in this market for one reason: they turn a seller’s “I’ll knock a few thousand off” into something you actually feel every month.
How a temporary buydown actually works
The “temporary” part is the whole point. Your loan has one permanent rate, the note rate, and that never changes. A buydown doesn’t touch it. Instead, a lump of money goes into a custodial account at closing, and each month the servicer pulls the difference between what you pay at the reduced rate and what the loan really costs at the note rate.
- 2-1 buydown: rate is 2% lower in year one, 1% lower in year two, then the note rate for years three through thirty.
- 1-0 buydown: rate is 1% lower in year one only.
- 3-2-1 buydown: 3% lower, then 2%, then 1%. Rare in Ohio because it’s expensive, but it exists.
Fannie Mae’s own rule (Selling Guide B2-1.4-04) caps the reduction at 3%, limits the step-up to 1% per year, and caps the structure at three years. Freddie Mac says the same thing in different words. Every 2-1 and 1-0 fits inside those rules.
The numbers on a $300,000 loan at 6.5%
This is the example I run for buyers most often, because $300,000 is a very normal loan around Cincinnati right now. The Greater Cincinnati median sale price was $329,450 in July 2026, and a buyer with a modest down payment lands right about here.
| Year | Effective rate | Monthly P&I | Monthly saving | Annual saving |
|---|---|---|---|---|
| 1 | 4.5% | $1,520.06 | $376.15 | $4,513.78 |
| 2 | 5.5% | $1,703.37 | $192.84 | $2,314.04 |
| 3–30 | 6.5% | $1,896.20 | 0 | 0 |
Add up the savings and you get the price tag:
- 2-1 buydown cost: $4,513.78 + $2,314.04 = $6,827.82, about 2.28% of the loan.
- 1-0 buydown cost: $2,314.04, about 0.77% of the loan.
That money is deposited into the buydown account at closing. It isn’t a fee that disappears. It’s your own future payment relief, prepaid.
These are principal-and-interest figures on a 30-year fixed, computed in September 2026 for illustration. Taxes, insurance, and any mortgage insurance sit on top. Your actual rate depends on your full scenario, and nothing here is a rate quote.
Who pays for it, and the rule that matters
In practice the buydown is almost always funded by an interested party: the seller, the builder, or occasionally a lender credit. Fannie Mae counts seller-funded buydowns against its interested-party contribution limits, which are 3% of the price when you’re putting less than 10% down, 6% between 10% and 25% down, and 9% above that. FHA caps seller contributions at 6% of the sales price. So on a $310,000 purchase with 3% down, the seller’s total help, buydown included, has to fit inside roughly $9,300. The 2-1 in the table above fits with room to spare.
The other rule, and this one protects you: you qualify at the note rate. Fannie Mae’s language is that the lender must “qualify the borrower based on the note rate without consideration of the bought-down rate.” FHA says the same. That means nobody can use a buydown to squeeze you into a payment you can’t afford in year three. If the $1,896 payment doesn’t work on paper, the loan doesn’t happen, regardless of how good year one looks.
One honest caveat: Fannie’s section names seller, builder, and lender funding. It does not spell out borrower-funded buydowns. If you wanted to pay for one yourself, that’s a conversation with me about whether a permanent buydown is smarter anyway. Usually it is.
2-1 buydown vs permanent buydown vs price cut
Sellers in Cincinnati and Columbus are willing to negotiate right now. Central Ohio had its highest July inventory in more than a decade (2.4 months of supply, Columbus REALTORS, July 2026), and Cincinnati’s median rose only 1.4% year over year. When a seller offers you money, there are three ways to spend it.
| Use of a ~$6,800 seller credit | What it does | Best when |
|---|---|---|
| 2-1 temporary buydown | Cuts payment $376/mo in year 1, $193/mo in year 2 | You expect to refinance or your income to rise within 2–3 years |
| Permanent buydown (discount points) | Lowers the note rate for the life of the loan, typically a fraction of a percent per point | You’ll keep this exact loan a long time and rates don’t fall |
| Price reduction | Lowers the loan by ~$6,800; saves roughly $43/mo in P&I at 6.5% | You’re near a loan-limit or down-payment threshold, or you just want the lowest balance |
The price cut is the weakest move for cash flow. Knocking $6,800 off a $300,000 loan at 6.5% saves about $43 a month. The same $6,800 as a 2-1 buydown saves $376 a month in year one. That’s why I steer most first-time buyers toward the buydown when the seller is offering a credit anyway.
The permanent buydown wins when you’re confident you’ll hold the loan for many years and rates stay put. I run both versions side by side for every client and let the numbers decide.
How to negotiate the credit in Cincinnati or Columbus
You don’t ask a seller for “a buydown.” You ask for a seller credit toward closing costs and prepaids, sized to the buydown you want, and your agent writes it into the purchase contract. A few things I coach buyers and their agents on:
- Know the number before you write the offer. A 2-1 on your loan amount has an exact cost. Ask me for it, then write the credit for that amount plus a cushion for closing costs.
- Offer closer to list, ask for the credit. A seller who nets $305,000 on a $310,000 contract with a $5,000 credit often feels better than one who accepts $305,000 flat, even though the math is identical to them. Their listing agent’s stats look better too.
- Builders love this. New-construction builders in the West Chester, Mason, and Delaware County corridors frequently advertise buydowns because it costs them less than dropping base prices across a whole community.
- Stay inside the contribution cap. If you’re at 3% down on a conventional loan, the total seller help caps at 3% of the price. On FHA it’s 6%. I check this before the offer goes out so nobody has to renegotiate at the closing table.
The honest risk: year three is real
A temporary buydown is not a gamble on rates. It’s a gamble on you. If rates drop in the next two years, you refinance and the buydown was a bonus. If rates don’t drop, you’re paying the full $1,896 in year three, which is exactly the payment I qualified you for. The buydown gave you two years of breathing room, nothing more.
Where people get hurt is treating the year-one payment as their budget. Don’t. Budget for year three, treat years one and two as savings, and put the difference somewhere useful: an emergency fund, principal, or the furniture you were going to put on a card anyway.
What happens to the money if you sell or refinance early
The buydown funds belong to the loan, not to the seller. If you pay the loan off early, whether by selling or refinancing, the unused balance in the buydown account is generally credited toward your principal at payoff. You don’t lose it, and the seller doesn’t get it back. The exact handling is spelled out in your buydown agreement at closing, and I walk through that document with every client so there are no surprises.
Is a 2-1 buydown right for you?
It fits best when three things are true: the seller is willing to credit you money, you’re buying a primary or second home on a fixed-rate loan (investment properties and cash-out refinances aren’t eligible under Fannie and Freddie rules), and you have a realistic reason to expect a better position by year three, whether that’s a refinance, a raise, or a paid-off car.
If that sounds like you, I’ll run your exact loan amount through both a 2-1 and a 1-0 and show you the permanent-buydown version next to it. It takes ten minutes. Start on the 1-0 and 2-1 rate buydowns in Ohio page, or if you’re a first-time buyer, the first-time home buyer and Ohio down payment assistance page covers how a buydown stacks with OHFA help.
Frequently asked questions
Does a 2-1 buydown lower my interest rate permanently?
No. Your note rate never changes. The buydown pays part of your interest for you in years one and two out of a prepaid escrow. From year three on you pay the note rate you were qualified at.
Can I pay for the buydown myself?
Fannie Mae’s rules name seller, builder, and lender funding and don’t spell out borrower-paid buydowns, so most lenders won’t structure it that way. If you have your own cash, a permanent buydown (discount points) or a larger down payment is usually the better use of it. I’ll show you both.
Does the buydown count toward the seller’s contribution limit?
Yes. Seller-funded buydowns count toward the interested-party caps: 3%, 6%, or 9% of the price on conventional loans depending on your down payment, and 6% on FHA. That’s why I size the credit before your offer is written.
What’s the difference between a 2-1 and a 1-0 buydown?
A 2-1 lowers the rate 2% in year one and 1% in year two. A 1-0 lowers it 1% in year one only. On a $300,000 loan at 6.5%, the 2-1 costs about $6,828 and the 1-0 about $2,314. The 1-0 is the fallback when the seller’s credit is smaller.
